Fig. 34 is an elevational view of the mechanism for placing a card in the bag prior to the filling thereof. Fig. 35 is a plan' of the above mechanism. Fig. '36 is a section on line A-A Fig. 34. Fig. 37 isa vertical section through the pivot of the folding device shown upon the left of Fig. 3 looking toward the left. Fig. 38 is a side elevation showing the means for effecting the vibratory movement of the funnel; and Fig. 39 is a sideelevation showing the o erative means for the dish carrying the poo ets for the. packet.

Referring to the appended drawings, 1 in-' dicates generally the frame of the machine sup orting a table 2 upon which are mounted t e various devices for effecting the operations for filling and closing the bags.

Mounted upon the up )01' end of a vertical Spindle 3 is a horizontally disposed wheel or isk 4 provided with a number of open chambers or pockets 5 closed at their lower ends by the table 2, with which the said ends are in close proximity. The s indle 3 receives its motion from a liOOthGt rod 6 Figs. 2 and 39, carried at its outer end in asuitable, guide 39 and at its inner end straddling the shaft 7 from which it receives motion through a cam 39 secured to the said-shaft and upon whic ln bears a roller 39 upon the rod. A sprin 39 is emplo; ed to keep the rolleralways Fearing upon the cam.

Actuated hj the toothed rod 6 is a pinion 8 lOOSG'lf mounted upon a shaft 9 Fig. 2, carried in the brackets 10 secured to the transverse v bar 11 of the supporting frame of the machine. 'lhe inion 8 carries a pawl 12 en gaging a rate et Wheel 13 secured to shaft 9 so that the motion of the pinion 8 in one direetion is transmitted to, the shaft and to aworm 14 secured to the shaft and operating a worm wheel 15 upon the vertical s indle 3. The arrangement is such that at eac 1 rcvolu tion of shaft 7 the pocket wheel makes {1 th. of a revolution. j

The shaft 7 is driven from the main shaft 1 7 through the pinions 17 and 18 secured respectively to the main shaft .17 and countershaft 7. Brackets such as '19, 20 are provided upon each side of the frame of the machine for the aforesaid shafts, and suitable driving-pulleys not shown in the drawings, are provided upon the shaft 17.

The bags may either be placed by hand in the chambers of the pocket wheel or where the packing machine is designed to-act in conjunction with a suitable bag making machine a device is provided into which the bags maybe thrust by the ejector of the said bag making machine. Further, in some cases it may be desired to insert a card into the bag prior to or after filling the same, or cards may be inserted both before and after the bag receives its contents. As, however, the card or cards wouldnot in all cases be required, in the general view the machine is shown with the mechanismfor introducing the said cards omitted.

The packingmachine' is in the present instance, shown as provided with a device to receive the bags from a bag making machine. lhe aforesaid device comprises a rectangular box like frame 21 Figs. 1, 2 and 7, which frame is secured to the end of a spindle 22 mounted upon the end of an arm 23 secured at its opposite end to the upper extremit; of a'vertical spindle 24. The arm 23 is adapted to oscillate toward and from the pocket Wheel about its pivotal axis, that is the axis of the spindle 24. A bracket 25 se cured to the table 2 supports the spindle 24 at its upper end while for the lower end of the said spindle a footstep bearing 26 is provided upon the lower side member of the frame of the machine. it at its ower end a toothed segment 27, Fig. 2, with which engage the teeth 28 upon the face of a horizontally disposed rod 29; The rod 29 at its outer end is supported ina guide 30 and at its other end straddles the shaft 7 and is provided with a roller 31 designed to l; ear upon the face of ah operating cam 32 Big. 22. A spring 33 shown in dotted lines in l 22 keeps the roller always incontact with the cam, one end of said spring being se cured to theguide 30 for the toothed rod 29 while the other end is attached tothe rod itseif. The spindle 22 aforesaid has secured to it at its opposite end to that carrying the frame 21; a short crank arm 34 to the outer end of which crank arm is pivotall attached by means of the pin 35 one end of a rod 36 the opposite end of the said rod being pivotally connected to the slotted head 37 mounted for oscillation upon the pin .38. A projection 39, secured to or cast integrally upon the upper end of thebracket 25, supports the pin 33 aforesaid. The position of the pivotal axes of the arm 23 and head 37, that'is in the present illustration the centers of the spindle 24 and the pin 38, is such that While the link The spindle 24 has secured to 36, connected through the crank arm 34 with the arm 23, rotates therewith at the same time the circle described by the outer end of the rod 36 is eccentric to that described by the arm 23 and consequently, assuming the receiver to be in the position shown in Fig. 7 the link 36 upon the angular movement of the s indie 24 will rock the arm 34 and the spin. le 22 to which it is connected, bringing the receiver into a vertical position above one of the pockets 5 as shown in Fig. 1. The receiver 21 in Fig. 7 is in ahorizontal position such that the bag when thrust off from the former of the bag making machine will be inserted 1n the said receiver, the open end of the bag being at that end of the receiver de-- signed to be uppermost when the said receiver is turned into the vertical position upon the horizontal movement of the arm 23.

The mechanism for effecting the removal of the bag from the receiver 2] and its introduction into one of the pockets 5 ma T comprise a weight such as 40 secured'to t 1e end of a chain or cord 41 passing over guide pulleys 42, 43 upon a bracket 44 secured to table 2. The chain at its lower end is'attached to the end of a weighted rod 45 operated by a cam 46 upon shaft 7 Figs. 2 andj23 and against which bears the roller 47 upon rod 45, the said rod being pivotally supported by a bracket 48 upon the frame of the machine. The mechanisms is so arranged that upon the pocket wheel coming to rest and the bag re ceiver being brought into its vertical position over the chamber in said wheel, the weight descends and carries the bag with it into the said wheel. The weight is then raised clear of the receiver.

The bag, after being placed in the pocket wheel is carried forward to receive its contents of some commodity, as for instance tea or the like which is weighed and delivered by suitable mechanism not forming part of the present invention. being delivered from the weighing machine falls into a funnel 49, the lower end of which no mally occupies a position above the mouth of the bag, but which, when the bag comes into position, is caused to be lowered and enter the mouth 0 the said bag so that the proper delivery of the tea or the like is insured.

In order that the necessary vertical move ment of the funnel may be effected, the said. funnel is mounted upon the'end of an arm 50 secured to the upper end of a vertical rod 51 carried in guides 52, 53, Figs. 1, 2, 30, 31 secured to the bracket 54 upon table 2. The

The tea or the like rod 51 is jointed to a rod 54 connected at its a bracket 58'secured to the lower end member of the frame of the machine v The bag when in position to be. filled, is supported or less level and so rafter receiving its contents is carried the bracket 63 before referred to.

upon a plate 59 of rectangular outline and of dimensions somewhat less than the area of the chambers on the pocket wheel. The upper surface of the plate 59 is normally flush with the upper surface of the table 2 and in order to assist the filling of the bag a vibratory movement is imparted to the plate shaking the bag and causing the contents to be shaken down therein, so that they are more permit the proper folding of the ends of the bag] The vibration of the plate 59'is effected by means of the toothed disk 60 Figs. 2 and 25 upon the periphery of which bears the lever 61 under the influence of the spring 62. i The lever is carried by an extension of the bracket 63 secured to the underside of table 2 and at its opposite end is provided with a head 64 designed to strike the lower end of the rod 65 to the upper end of which plate 59 is secured and for which plate an opening is formed in table 2. The rod 65 is supported in guides 66 fornicdn ippn esired a similar vibratory movement may be imparted to the funnel 49 to prevent the tea or the like cloggingorhanging therein. This may be effected by providing the smaller diameter of the cam 57 with projections 57 as shown in Fig. 38 so that dur ng the passage of the roller 56 thereover a vibratory movement will be imparted to the funnel which will shake the tea there.n and prevent it clogging or hanging in. the funnel and so insure its discharge into the packet. The bag forward by the pocket wheel and is next placed in a position for two of the sides to be folded inwards. the contents of the bag being first rammed or pressed down. During the first I folding operation gum is applied to the secarms 69, 70 forming 0nd fold so that the first fold s are secured together, the final folds being secured if desired, by means of a gummed label placed thereon by hand.

The mechanism for effecting the above operations comprises a block 67 secured to the end of a rod 68 carried in guides upon the part of the bracket 7], which bracket is bolted orotherwise secured to the table 2. The bracket 71 is bifurcated at its lower end so that it straddles the folding mechanism as shown in Fig. 3. The block 67 has secured to it two small brackets 72 designed to carry the ends of the spindle Of a gum roller 7 3, and which roller receives gum from a roller 74 rotating in a gum reservoir 75 carried u'mn brackets secured to the table 2. The re or 74. just referred to is rotated by means of a lever pivotally secured to one of the rods 7 6, 77 carrying the folders to be presently more fully described.

78 indicates a ratchet wheel upon the rocking lever 75) freely mounted upon the spindle of the aforesaid gum roller 74, and to the lower end of which lever is secured the end of the rod 80 connected at its opposite end to a boss 81 upon the rod 76. it will be obvious that upon the reciprocation of the rod 76, the roller 74 will be causcd'to rotate and gum be transferred from the container 75 to the roller 73. The vertical reciprocation of the block 67, the dimensions ofwhich are such as topermit it to readily enter the mouth of the filled bag, is effected by means supported by extensions 84 secured to the brackets 84 supporting the folders. The upper end of lever 82 is connected by means of links such as 85 with a block 86 secured to the upper end of rod 68 and movement is imparted to the lever by means of the rod 87, at its lower end straddling shaft 7 and carrying a roller 88 bearing upon the edge of the cam 89, see Fig. 28. A counterweight 90 serves to keep the roller 88 in contact with thecam. The horizontal rods 76, 77 before referred to are supported inguidcs such as 90 formed integralvith the upper surface of the brackets 84. The rods are connected by means of the transverse bars 91, 92 each bar being provided with a depending foot like extension 96 to which are pivotally secured the folders illustrated in Figs. 3 to 6 and 15 to 19. The folders comprise shoes )3 having outwardly inclining sides )4 and in which are secured in any convenient manner the U shaped castings 95 between .the vertical walls of which passes the extension 96 forming part of the transverse connecting bars ill, 92 aforesaid. A pin 97 )asscs through the walls of the casting 95 an the extensions 96. Each folder is niaintaincd in its normal position by means of springs 98 connected at one end to a convenient portion of the folder and at the other to a pin upon the extension 96. The inclined lower portion 9!) of the extension coming into contact with the upper surface of the basc of part 95 limits the movement of the folders under the action of springs 08.

it will be seen on reference to the drawings, that the folder upon the right hand side in figs. 3 and 15, is provided with a piece of rubber or other suitable substance 100 clamped by means of the plate 101 to the transverse plate 102 formed inicgral with the shoe. The casting 95 is cut away for the passage of the plate 102. When in its normal position the rubber projects into the path of the um roller 73 so that upon the descent of t 10 block 67 the roller thereon comes into contact with the rubber or the like 100 and applies gum thereto substau-' tially as shown in .l 'ig. 1. Upon the withdrawal of the block 67, the purpose of which as already described being to tents of the bag down to a vel approxilpress the corn &

mately even with the top of the chamber in the upstanding side of the en of the bag.

The folder continuing its movement f'olds the side down and eventually the tail end of said folder comes into contact with a roller 103 arran ed transversely of and in the path of the fo lder, so that the folder is tripped against the action of its spring and brought into a horizontal osition as shown in Fig. 5 press ing the fol ed portion down upon the top of the contents of the bag. At the same time the rubber 100, to which as above described, gum has been applied, comes into contact with the opposite upstanding portion of the bag and applies gum. thereto. The roller 103 before referred to is supported by .a s indle 104 carried by arms 105 secured to t 1e inside of the brackets 84. Upon the withdrawal ofthe right hand folder the left hand folder advances and folds the 0 posite side of the bag and during its forwarc move ment is tripped by means of a bar 106 ,ar

ranged transversely of its path, pressing the folded portion down upon the first fold to which it will adhere by reason of the gum a plied to its inner surface. Upon the withdrawal of the second folder the parts are re-i turned to their original positions as shown in F 3. The reciprocation of the folders is effected by means of a cam 107 secured to shaft 7, Fig. 27 and with the groove in which engages a roller 10% secured to the lever 109 pivotally supported upon the bracket 110 secured to the transverse bar 111 upon the end members of the frame, see Fig. 2. The lever 109 at its upper end connected by means of links 112 with a projection u on the outermost bar 112 connecting the fo der rods.

During the folding operations above described the sides of the bag are prevented from bulging or becoming otherwise damaged by means of the wedge shaped plates 1 1 3, the'inclination of which is approximately that of the sides of the shoes 93. The plates are carried by the extensions 11 1 upon the end of a slide 115 which slide is arra-n ed to reciprocate horizontally between the rackets 84. The dimensions of the partsare such that when the shoes are.in position between the plates 113 there is just'sullicicnt clearance between them to accommodate the upstanding sides of the bag. To prevent dam- .age to the bag any sharp edges thereon which might come into contact with the bag are rounded off. The inclination of the plates 1-13 and of the sides of the shoes causes the sides of the bag not beingoperated upon to be bent or turned out of the way and at 1 thesame time does not injure them so that they cannot afterwards be properly folded. By t'his'means'the final folding may be pertransverse bar- 111 aforesaid. V withdrawal of the folders and side plates the pocket wheel is again rotated and comes to.

amnes a fectly accomplished and the end of the packet present a neat appearance. movement of the slide 115 is effected by means of a cam 116 Fig. 26, secured-to shaft 7 and with the groove 'of which engages a roller 117 secured to the lever 118 pivotally supported by the bracket/1 19 secured to the Upon v the rest in a position intermediate of the two sets offolding devices, the next movement bringing it into a position ready for the final. folding operations. The folders for effecting the above operation comprise a pair of plates such as 1111 supported upon pins 120 pass- 'ing through lugs 121 formed upon the angle 7 plate 'OI' bracket 1.22 secured to the front of the bracket 123 bolted or otherwise secured to the table 2, see fl igs. 1. and 10 to 1- 1 of the accompanyingdrawings. 1;he ends of the pins are provided with portions 12st bent at a right angle to the body thereof and to these are connected the lower endsof springs 125,

the upper ends of said springs being secured to the turned over port ion 126 of the pin 127. Under the act-ion; of the springs the plates ticab rod I 129 1 formed upon the bracket 123. Also secured to the rod 129 is a forked plate :130 straddling, the block 128 as shown 'in Figs. 11 and'12: The vertical portions of the plate are tapered, being thickest at their outer ends. The plate 130 operates the folders upon the downward movement ofrod 129, the vertical The 1119 have a tendency to assume a horizontal position as shown inFigs. 10 and 12/ the 4 angle plate 122 is perforated for the passage of the presser block 1-28 secured to the ver for which suitable guides are portions ofth'e plate130 coming into contact a with the plates 1 19 when in their horizontal positions, causing them to swing inwards againstthe action of the springs 125 when they come into contact with the upstanding sidesof the bag and fold same inwards. The plates 119 are channeled at 131 and at the upper end of said channels are provided with projecting plates of wedge shaped lon. I

gitudinal' section 1.32. The channels and the plates are clearly shown in Figs. 13 and 1 1. The purpose of the projections is to cause the plates to first swing, inwards as indicated by the dotted lines in Fig. 11 by the:

lower and thicker portions of the vertical members of forked plate 130 cominginto contact with the projections 132 upon the said plates. Upon the ends of late1 30 clearing the projections 132 the felt ers under the action of their springs, oped outwards, leaving a clear passage between them for the presser block 128 which block coinesinto contact with and'presses the final folds of the bag remaining in contact therewith durmg the period of rest ofthe pocket when...

' 7 upon which bears a roller 134 upon a rod 134 which at its lower end straddles the said shaft 7 as shown in Fig. 29. 'l he upper end of the rod is connected to a lever 135 su ported by the bracket 136 se ured to the ace of the table 2, the opposite end of the lever being connected bymeans of the links 137 to the block 138 upon rod 129. A spring l38 shown-in'Fig. 1 keeps the roller 134 always in contact with the cam.

The further successive movements of the pocket wheel eventually brin s the packet lnto line with mouth of the c ute 141 into which it is delivered. The packet-when the wheel is in the position just referred to, rests upon a rectangular plate 140 for which an opening'is formed in the table 2. The dimensions of the plate are such as to permit it to freely enter the chamber in the; pocket wheel, in order to raise the'packet until the bottom thereof is on a level with the bottom Bi ths discharge chute 141, -Fi 1 and into which chute the packets are t rust b the plate 142 secured to the end of the ro 143. 'lherod 143 is carried by the outerconnectingbar oF-the rods '76, 77 and reciprocates with-the said bars. '1 he movement of the plfite 140 is. effected by means of the cam 144 secured to shaft 7. and which cam operates a lever 145 pivoted upon the main shaft '17. v The outer end of lever 145 is connected to the.lower end of a rod 146 to the upper end of which the plate 140 is secured as tsh'own ilp Fig. 33.

It is und in practice that the height of the packet will var in accordance with the material w'hichis eing packed. Thus for example, small leaved tea can be compressed .into smaller dimensions than tea having a coarse leaf. Under these latter circumstances, it is found that the height of the packet after the compression of its contents is greater than in the first case and consequentl in order that the folding may be proper y performed that the various folding devices need adjustment. In order to avoid the aforesaid adjustment of the folders I employ the arrangement shown in Figs. 20

and 21 in which 147 indicates a plate secured beneath an opening 148 formed in the table 2, such opening being of circular outline and extending in the present instance for a distance equal to one fourth the circumference of the pocket wheel and equal in Width to the internal width of the chambers therein. The opening is shown in dotted li es in Fig. 21. The plate 147 is connecte by means of studs or bolts 149 to the underside of table 2. and is provided wlth Wedge shaped projections 150 upon its undersid such pro ections engaging the inclined ;faces of the projections 151 upon the upper face of plate 152. The plate 152 is secured to the table by the bolts 149 aforesaid, which are provided with nuts 153 for this purpose. Distance pieces or lugs 154 upon the plate 152 serve to keep it in its proper position with regard to the plate 147.

The plate 152 is slotted for the passage of the bolts 149, springs 156 being interposed between the two plates 147 and 152 as shown in Fig. 20. To adjust the height of the packet, plate 147 is raised or lowered by moving the plate 152 by means of the set screws 156 passing through screwed bosses 157 formed upon the underside of the table 2. The inner end of each screw 156 passes through the distance piece upon the plate 147 and is provided with a collar and lock nuts as shown in Fig. 20. By moving plate 152 to the right or left the upper plate 147 is caused to e raised or lowered as will be 'readily understood on referring to the drawings. The packets are pushed down upon the plate 147 by the rammer acting in conjunction with the gum distributing roller and are raised until upon a level with the upper surface of table 2, upon reaching the en of the opening 148 by the plate 158 op- ;erated from the main shaft by means of a suitable cam and lever as in the case of the other similar plates to which reference has previously been made.

-Figs. 30 and 31 illustrate an alternative form of apparatus for effecting the removal of the bags from the receiver and inserting them in the pocket wheel. Secured to or formed integral with the upper end of bracket 54 carrying the funnel 49 is an extension 159 having at its upper end a horizontal portion 160 provided with two bosses 161, 162 perforated for the passage of rods 163, 164. The rods 163, 164 are connected together at or near their upper ends by means of the bar 165, the rod' 163 being so disposed that it is normally above and coincident with the vertical center line of the bag when it is in a position to be placed in the pocket wheel. The rod 164 is at its lower end provided with teeth desi ned to engage a sprocket wheel 167 secured to one end of a spindle 168 "supported at one end by the bracket 54 and at the other by means of a bracket 169 secured to table 2. opposite end the spindle 168 is provided with a pinion 171 engaging a vertical reciprocating rod 172 having teeth upon one face and operated from the shaft 7 by means of a cam such as.173 with the groove of which en agcs-the roller 174 upon the lower end of I'0( 172 aforesaid. Upon the reciprocation of the rod 172 the rod 163 comes into contact with the bottom of the empty bag in the receiving device and thrusts it into the chamber of the pocket wheel.

As aforesaid, cards may be inserted in the At its bag prior to or after it has received its contents or both before and after this operation.

In Figs. 34, 35 and 36 is illustrated mechanism for effecting the introduction of a card into the bag prior to filling the same.

The means for performing the above oper-' ation in the case where the card is to be inserted prior to the filli' .g of the bag comprises a vertically disposed tube 175 which is substituted for the rod 163 shown in Figs. 30

and 31 which rod passes through the boss 161.

upon arm 160 carried by bracket 159. In the present instance, the tube is provided at its lower end with a pair of lates 176, 177' between which are clampe the heads of spikes or pins 178 which ins project through apertures formed in a p ate 179 which late is secured to thelower end of the roc 180 contained and working within the tube 175 aforesaid. The tube ust referred to is secured to the bar 1.65, the opposite end of which bar is connected to the vertically reciprocating rod 164. The upper end of rod 180 is pivotally'secured to the end of the lever 181 carried by a column 182 secured to the upper surface of the bar 165. posite end of the lever 181 is under the inlluence of a spring 183 the action of which causes the plate 179 upon the rod 180 to be normally pressed against theplate 177 so that the ends of the pins project below the surface of the said plate 179. The separation of the plates is effectedby means of the stud 184 which is adjustably secured to the arm 160 of bracket 159 and which, upon the bracket 159 is an arm 186 to which is secured by bolts 187 a plate 188. The plate 188 is slotted for the passage of rack 189, Fig. 36,

which issecured to the underside of a slide 190 running in guides 191, 192. The rack 189 is engaged by a toothed sector 193 shown in dotted lines in Fig. 34 which sector is secured to: the extended upper end' of the vertical spindle 24 carrying the receiver for the bag. The slide upon the rotation of the spindle 24 is thrust forward and is brought into a position beneath the plate 179 carrying with it a card from the magazine 19;. The plate is then caused to descend and the pins enter tlie card which upon the upward movement of the plate is lifted. The necessary movement is obtained by the addition of a suitable cam surface to the cam operating the vertical rack 178,"shown clearly 111 The op-" card, which as will be presently de-- with or secured to the Figs. 30 and 31. Upon the upward movement of the plate 179, the slide is withdrawn from the path of the plate, which upon the receiver 21 coming into position thereunder, descends, forcing the ba into a pocket of wheel 4. The card is re eased as aforesaid when the rod 164 approaches its point of lowest movement. A similar arrangement to-that just described may be employed in conjunction with the block 67 so that two cards ma be introduced into the packet one beforefil ing and one after the bag has been filled, and prior to closim the end thereof.

The full operation of the machine can be clearly ascertained from the foregoing description, it being understood that the various necessary operations for the filling and closing of the. bag are effected successively during the periods of rest of the pocket wheel.
